Monitor Mix / Solo Bus

32 bit floating point processing

32-bit floating point processing

Virtually infinite headroom

Finely crafted vintage compression

The Leveler™ is an accurate model of the legendary Teletronix™ LA-2A™ optical leveling amplifier, known for its unique and highly sought-after Automatic Gain Control (AGC) characteristics. The heart of the LA-2A is the T4 opto-coupler, a photoelectric device with almost magical (signal dependent) self-adjusting behavior that makes optical compressors the tool of choice for smoothing out just about any audio material.
